Here is how I installed and configured LTSP on Linux Mint 13 32-bit. My LTSP server has two network cards, eth0 connected to internet through a router and eth1 for ltsp clients.
1. Install package “ltsp-server-standalone” using apt-get:
sudo apt-get install ltsp-server-standalone
or synaptic:
2. From console (terminal) execute following commands:
sudo cp -R /usr/share/ltsp/plugins/ltsp-build-client/Ubuntu /usr/share/ltsp/plugins/ltsp-build-client/LinuxMint sudo ln -s /usr/share/debootstrap/scripts/gutsy /usr/share/debootstrap/scripts/maya sudo sed -i 's/DIST=${DIST:-"$(lsb_release -s -c)"}/DIST=${DIST:-"precise"}/' "/usr/share/ltsp/plugins/ltsp-build-client/LinuxMint/000-basic-configuration" sudo ln -s /usr/share/ltsp/plugins/ltsp-build-client/Debian-functions /usr/share/ltsp/plugins/ltsp-build-client/LinuxMint-functions
3. Build ltsp client:
sudo ltsp-build-client --arch i386
4. Add following entry to “/etc/network/interfaces” file:
auto eth1 iface eth1 inet static address 192.168.0.1 netmask 255.255.255.0
5. To make sure dhcp server only response to the second ethernet card, put interface “eth1” to file “/etc/default/isc-dhcp-server”:
INTERFACES="eth1"
6. At this point LTSP server is ready, you can try it by restarting the server and boot ltsp clients from network. But we want to go on setting up guest accounts. To activate guest account, create a new lts.conf file “/var/lib/tftpboot/ltsp/i386/lts.conf” and add following lines:
[Default] LDM_GUESTLOGIN=True LDM_PASSWORD=secret
7. Add guest user names:
sudo adduser ltsp20 sudo adduser ltsp21
8. Now you can try to login from ltsp client using guest account.
9. Now we want to automatically clean up guest home directory every time guest log in. Create a new file “/opt/ltsp/i386/usr/share/ldm/rc.d/S00-guest-sessions” and put following text in it:
case "$LDM_USERNAME" in ltsp*) ssh -S "$LDM_SOCKET" "$LDM_SERVER" 'cd; rm -rf .* *; rsync -a /etc/skel/ .' ;; esac
10. Save the file and run “ltsp-update-image”:
sudo ltsp-update-image
11. Install “epoptes” using apt-get:
sudo apt-get install epoptes
or synaptic:
12. Add user to group epoptes:
sudo gpasswd -a <username> epoptes
13. Install epoptes-client to ltsp client:
sudo chroot /opt/ltsp/i386 apt-get install epoptes-client epoptes-client -c exit
14. Update ltsp image:
sudo ltsp-update-image
15. Reboot the server, start clients and run epoptes.
16. Fix for Mate desktop manager. Save following script as “endsession”:

17. Copy file “endsession” into directories “/usr/share/epoptes-client” and “/opt/ltsp/i386/usr/share/epoptes-client”:
sudo cp endsession /usr/share/epoptes-client sudo cp endsession /opt/ltsp/i386/usr/share/epoptes-client
18. Update ltsp image:
sudo ltsp-update-image
19. As I want to use this server for demonstration purpose, I want to clear up dhcp lease every time the server boots. To do that just add these two lines into file “/etc/rc.local” above line “exit 0”:
rm /var/lib/dhcp/* service isc-dhcp-server restart
20. That’s it. Enjoy your new LTSP system!
